In a flash of white light, Qin Yu appeared in the apartment he rented in New York City, where he was offline, the sun was shining outside the window, and it looked like the weather was good.

Without delay, Qin Yu decided to go back to Kama Taj directly.

A secret door easily opened a passage to the other side of the earth, and walked straight over, this feeling of powerful mana is really nostalgic, in reality, his mana is much worse, and it takes a lot of effort to open a door for dozens of kilometers.

Passing through the portal, Qin Yu was stunned, and it was dark in front of him.

Damn, what's the situation? Why is this the black sky?

He was stunned for a while before he reacted, it stands to reason that during the day in New York, the Kama Taj on the other side of the world should indeed be night, but the game time was synchronized in the past, and he didn't realize this problem at all, and now it seems that the game has been patched and upgraded to fix this problem, but it's still a little unaccustomed.

But soon Qin Yu came back to his senses, after all, he had also been reborn, and he had encountered this situation before, so he quickly adjusted his mentality.

Looking at the familiar scene of Kama Taj in front of me, I couldn't help but feel a little nostalgic and affectionate in my heart.

It's finally back again, Qin Yu thought. ’

Behind him, another portal opened, and Lawless walked out of it.

"Hey, Merlin, you're online too, long time no see, how have you been doing in the last few days, have you had any Internet addiction attacks?"

Qin Yu smiled, "I've had a very thrilling past few days, you know the incident that broke out a few days ago, my home is in Xijiang City." ”

"Holy! Really fake!? The lawless one was stunned for a moment, "Then have you seen those alien bugs?" Is it as scary as it is reported online? ”

Alien bugs? Qin Yuxin said that you really dare to think about it, but think about it, ordinary people may not be able to accept any other worlds, extra dimensions and the like, it is more reasonable to be an alien creature.

"It was quite scary, a lot of people died, and I went to look at it afterwards, and I only saw the corpses of some monsters, but it was still scary."

As the two of them spoke, one after another arcane doors sprung up, and more mage players appeared in Kama Taj's square.

While greeting each other to acquaintances they knew, while discussing what happened after going offline in the past few days, as well as the excitement of meeting again, Qin Yu had a feeling of meeting his classmates at the beginning of the new semester, Qin Yu had to admit that the sense of belonging brought by this game was very strong, and looking at the players around him felt really like watching a group of classmates and friends studying together.

With the appearance of a large number of players, the Kama Taj, which was originally somewhat quiet, soon became lively.

Everyone chatted and discussed, and the content of the chat was naturally indispensable for the monster invasion incident.

A player suddenly said, "By the way, have you noticed that these monster invasions feel a bit like the combat missions we usually do, do you think there will be extra dimensions in reality, or places like other dimensions?" Those monsters can't have come from another universe, right? ”

Qin Yu glanced at the man, but it was a reloaded magic god, this brain hole was quite big, and he actually guessed the truth to a certain extent-although Qin Yu himself guessed, but he basically felt that this should be the case.

"Come on, reality is not the same as games, there is no extra universe, you shouldn't be too much sci-fi."

Someone immediately sneered.

Seeing that a debate was about to begin, Qin Yu left the crowd and walked straight towards the library.

Instead, he wanted to see if there were any books in the library that could solve his puzzles.

When she walked into the library, to Qin Yu's surprise, Gu Yi was actually here, she was talking to Wang about something, and stopped talking at the same time when she saw Qin Yu walk in.

"Merlin, where have you been lately, why haven't you seen you?"

Qin Yu was shocked when he heard this, and said in his heart, obediently, could it be that the time in the game is still going on during this time?

"There's been a lot of work to take care of lately."

"Well, now that you're done, continue your studies, and continue to practice spatial manipulation tomorrow, no problem, right?"

"No problem," Qin Yu said hurriedly.

Seeing that Gu Yi was leaving, Qin Yu was anxious, "Master Gu Yi, the disciple has some questions that I want to seek your answers. ”

"What do you want to ask?" Gu Yi has an attitude of teaching by word and deed.

"I want to ask what exactly is the relationship between space, time, and dimension?"

Gu Yi pondered for a moment and said: "Space plus time equals dimension, the world we live in is a huge space, and time flows in it, just like the water in a water tank, we are the fish in the water."

Between dimensions and dimensions, it is like two different water tanks, although they are close to each other, but the water inside has its own direction.

Space magic is the safest, although it is already magical for ordinary people, but for us, it is the most commonly used magic, using space magic, it is like blowing a few bubbles in a water tank, it looks magical, but it will not affect this water tank.

The reason why time magic is dangerous is that time magic is like stirring the water flow hard, although the water flow is unlikely to cause damage to the water tank, it may affect the stability of the water tank, and this is a very dangerous behavior, because it may hit other water tanks.

As for dimensional magic, it is the most dangerous magic, just like a fish jumping from one tank to the next tank, you have no idea what other tanks are filled with, it may be water, it may be oil, any attempt to explore additional dimensions can have terrible consequences, if you are lucky, you will only harm yourself, and if you are unlucky, it can even bring a threat to our whole world.

The only difference is the mirror dimension, which overlaps with the reality dimension, so it has the same speed of time, which is one of the few dimensional magic that can be used safely. ”

I see! When Qin Yu heard this, he suddenly understood.

Because different dimensions have independent time streams, if the time of one dimension changes, the other dimensions will not change accordingly.

At the beginning, I used the Infinity Gauntlet to reverse time, but it was only the time of my own world, and the time of other dimensions or worlds was still operating in a normal direction.

That's why the invasion of the other world will only happen after he is reborn, because even if he doesn't reverse time, those monsters will enter the earth, but only eight years later.

Now Qin Yu finally understood, it seems that this matter is not his own relationship - well, strictly speaking, he actually advanced the invasion by eight years, but the invasion itself is inevitable, so it is not all his own pot.

"Thank you, Master, for your doubts."

Gu Yi nodded, "Why are you asking this?" ”

Qin Yu explained: "It's just that there are some doubts. ”

"I want you to try not to use dimensional magic or time magic, because when people think they're playing with time, they always end up reaping the consequences."

Qin Yu was stunned for a moment when he heard this, and said in his heart that there was some deep meaning in his heart, and when he looked up again, Gu Yi had already left.
